Osmosis: Definition, Types, Examples (Osmosis vs Diffusion)

Osmosis is a biophysical process occurring commonly in biological systems where solvent molecules move across a semi-permeable membrane towards a region of high solute concentration.

• It is a type of passive transport and is directed towards the direction that tends to equalize the solute concentration across a semi-permeable membrane.
• It is a common process taking place in most of the biological membrane in the organisms.
• In a biological system, the solvent mostly is water; however, osmosis can also take place in other liquids and even gases.
• As it is a means of passive transport, it doesn’t require any energy.
